1. Description
Optical Sensor
The LTR-559ALS-01 is an integrated low voltage I2C digital light sensor [ALS] and proximity sensor [PS] with built-in emitter,
in a single miniature chipled lead-free surface mount package. This sensor converts light intensity to a digital output signal
capable of direct I2C interface. It provides a linear response over a wide dynamic range from 0.01 lux to 64k lux and is well
suited to applications under high ambient brightness. With built-in proximity sensor (emitter and detector), LTR-559ALS-01
offers the feature to detect object at a user configurable distance.
The sensor supports an interrupt feature that removes the need to poll the sensor for a reading which improves system
efficiency. The sensor also supports several features that help to minimize the occurrence of false triggering. This CMOS
design and factory-set one time trimming capability ensure minimal sensor-to-sensor variations for ease of manufacturability
to the end customers.
